In each of the cases below, decide whether the indicated protein would be synthesized by a free ribosome or by an ER-docked ribosome. 1. Protein kinase A is an enzyme in the cytoplasm involved in signal transduction of GPCR. 2. Glycotransferase is an enzyme that adds sugars to proteins in the Golgi Apparatus. 3. RNA polymerase 4. A chimera protein that has both the SRP binding signal and a nuclear localization signal. 5. A hormone produced in the brain that targets the heart muscle. Cytochrome c oxidase is an enzyme involved in the synthesis of ATP in the mitochondrion.

Step 1
Protein kinase A is an enzyme in the cytoplasm involved in signal transduction of GPCR. Since it is located in the cytoplasm, it would be synthesized by a free ribosome. $$\boxed{\text{Free Ribosome}}$$ Show more…

Drag and drop each type of protein into the correct category: is it synthesized on free ribosomes or RER-membrane-associated ribosomes? Free cytosolic ribosomes RER membrane-associated cytosolic ribosomes No Answers Chosen No Answers Chosen Possible answers: LDL (low density lipoprotein) receptor mitochondrial protein encoded by a nuclear gene SRP signal recognition particle transcription factor K+ channel protein GPCR (G protein-coupled receptor) hexokinase, which catalyzes step 1 of glycolysis SRP receptor docking protein lysosomal enzyme, hexosaminidase beta-tubulin (subunit of a microtubule)

In a eukaryotic cell, what would be the location of protein synthesis for: Protein found in the matrix of mitochondria? A. Free Ribosomes in the Cytosol B. Surface of the ER C. Either of these D. None of these 2. In a eukaryotic cell, what would be the location of protein synthesis for: Nuclease in the lysosome? A. Free Ribosomes in the Cytosol B. Surface of the ER C. Either of these D. None of these 3. Place the following events involved in signal hypothesis in the correct sequence: A. Ribosome finishes/terminates translation on the RER B. SRP binds to the signal sequence C. mRNA leaves the nucleus D. Growing polypeptide chain enters the lumen of the RER E. SRP-Ribosome-mRNA binds to the SRP Receptor on the RER F. Ribosome begins the process of translation
